The correct option(s) regarding to the complex 
${\left[\text{Co}\left(\text{en}\right){\left({\text{NH}}_{\text{3}}\right)}_{\text{3}}\left({\text{H}}_{\text{2}}\text{O}\right)\right]}^{\text{3+}}\left({\text{en=H}}_{\text{2}}{\text{NCH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{NH}}_{\text{2}}\right)$

It will have three geometrical isomers if  bidentate ‘en’ is replaced by two cyanide ligands

It has two geometrical isomers

It is paramagnetic

It absorbs light at longer wavelength as compared to ${\left[\text{Co}\left(\text{en}\right){\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}\right]}^{\text{3+}}$
